RAILWAY TIE.

Application filed November This invention relates to railway ties andparticularly to eomposite ties of cement and metal.-

The object of the invention is to provide railway'ties of simple andpractical construct-ion each coniprising a pair of spaced blocks ofplastic composition and connected together by pliable metal rodsarranged to maintain the. blocks in suitable relative po sitions. v

A further object of the invention is the provision of a. ailway tieformed of separate blocks under each of the rails, respectively,suitably formed to receive metal retaining rods to maintain the blocksin aligned positions and the rails at their proper gauge Width.

A still further object of the invention is the provision of sparkedconcrete blocks for supporting the rails and metal rods for tying said,blocks in transversely disposed pair's, said blQ ks being grooved ontheir lateral surfaces to receive said rods ext-ernally at selectiveelevations.

A still further object of the invention is the provision of concreterailway ties pro vided with novel means for retaining the rails indetachably so? fed; position thereon.

Other objects and advantages of 1y invention, and objQCiiS relating todetails of constructionand arrangement of parts, will be readilyapparent in the course of the detailed description to follow.

Referring to said views, the reference numeral 1 indicates a blockformed of con crete or other suitable plastic material which 15, 1927.Serial No. 233,358.

is substantially rectangular in plan and in end elevation. One of saidblocks is designed to be placed under each of a pair of rails 2,respectively, the major axes of the locks being in alignment anddisposed transversely to the line of therails. The bottom surfaces ofsaid blocks are desirablv of greater depth in their middle portions thenat their two extremities; said surfaces being of Curved configuration,as indicated in Figjl. or of angular configuration. shown in I igfs. A"kite tamping of the road bed therjunder. "The upper surfaces of theblocks are formed with a centrally disposed transverse channel 5 in itscentral portion to receive the 2, said channel being of greater depththan the edges of the rail flanges 6. I

Retaining spikes 'Z' of malleable metal are imbedded vertically in tlillo ck upon" each side of said channel, their-inner surfaces beingsubstantially flush with the respective lateral edges of 'the channel.Said spikes are formed with a laterallyextendin anchor portion 8 at thelower end, vi, they are permanently ret-ainedin the concrete, and beforeassembly the upper pro jecting portions of the spikes extend verticallytherefrom Desiralily a pair of said spikes are positioned u'pdii eachside of the rail retaining chann lin oppositely spaced relation, anduponthe mountiiig'oi the rail upon the block said projecting ends of thespikes are bent over upon the rail flanges to fixedly secure the rail tothe block.

Adjacent eaeh lateral edge of the block and immediately below thesurfaceoi the channels a bar 10 of corrugated metal is imbedded in theblock material to reinforce the edges of the channel and safeguar thesame fronifracture. Each of the bloclis is formed "with an aperture" 11extending l'ongitudinally thereof in vertical line with its major axis.A metal rod" 12 is passed through said aperture and eritends throughlimilar aperture in the companion opposblock. Said rods project from theouter e of said apertures Where they are screw tareaded to receive nuts13 to bear upon a Washer 15, as shownin Fig. 1, contacting with therespective block-end or. shown in Figs. 2 to 4, inclusive, upon a metalplate 16 apertured to accommodate said rod.

The blocks are formed on their lateral surfaces 17 with a plurality ofgrooves 18 of llO tally and parallel. Mot-a] rods 20 are received insaid grooves further connecting each pair of blocks together throughtheir e2: being extended through apertures of the metal plates 16 andfixedly secured thereto nuts 21 engaged on the thre deal ends of therods engaging said plates with the desired amount of tension. The endapertures of said plates being in register with the grooves 18 maintainthe rods in close ongagement in the respective grooves, and they may hefurther maintained in such engagement by a tie plate 22 provided withapertures through which the rods may be threaded and positioned in thespace intermediate the inner ends of the blocks.

As further security for the rail against lateral displacement, as uponthe outer side of curves in the track, rail braces 2-3 may be secured tothe outer block of the curve to take up the lateral thrust. Said railbraces may be formed with a body 25 engaging the outer side of the railand a flange 26 provided with a pair of apertures registering with apair of spaced recesses 27 extending vertically from the upper surfaceof the block through which expansion bolts 28 may be inserted throughthe flange of the rail brace to rigidly secure the same to the block.

In practice the rail blocks are positioned in opposing relation andadjusted to the proper rail gauge by means of the tie rods 12. The ra1ls2 may then be seated in the channels 5 and rigidly secured therein bybending the spikes 7 over upon their opposing flanges. For light railsthe tie rods 12 may be sufiicient t-o retain the blocks in position.Where heavier traffic is borne, or upon curves, the tie rods 20 areadded to more efliciently maintain the tie blocks in their relativepositions. The rods 20 may be disposed in the upper pair of grooves 18which will be substantially in alignment with the tie rods 12 andslightly above or following the surface of the road bed. F or heaviertrafiic the lower grooves may be employed in which the rods 20 aredisposed, in which arrangement the rods 20 and the rods 12 will lie inthe apices of a triangle, thus giving more rigidity as the lower rodswill be imbedded in the road bed. For extremely heavy traific two ormore pair of rods 20 may be employed. To this end I have provided ametal plate 30 (see Fig. 6) to engage the outer end of the blocks andwhich is apertured, as at 31, to receive a plurality of rods 20 on eachside.

The advantages of my invention resides in its adaptability to allconditions of railroad building in that it may be utilized forsemi-circular cross section extending horilight track at a minimum oftie rod inai ai or with the same form of block adoual metal may he addedto meet the requzrements or traffic as the same is demanded. Theindividual locks are of simple co .:tructic-n and economical ofmanufacture are readily transported and handled, the expense of buildingand maintenan e may be kept at a minimun.

From the foregoing description, talren in connection with theaccompanying drawing, the advantages of the construction and applicationof my invention will be readily apparent; but, while I have describedthe principle of 01 eration of the invention, together with the deviceswhich I now consider the best embodimentthereof, it will be understoodthat the structures shown are merely illustrative and that such changesmay be made therein as will lie within the scope of the followingclaims.

Having described my invention, what I claim, is:

1. A railway tie comprising a pair of railsupporting blocks each formedwith a transverse rail-receiving channel, means to secure rail in saidchannel, said blocks being formed with a longitudinally disposedaperture and a plurality of horizontally arranged grooves in its lateralfaces parallel with said aperture, 3. tie rod extending through saidaperture and provided with nuts screwed on its projecting ends to securesaid blocks in adjusted positions, a pair of tie rods disposed inselected of said grooves having screw threaded ends, a plate engagingthe end of each block. apertured in register with said grooves throughwhich said pair of rods extend upon opposite sides of the block, andnuts screwed upon the ends of said pair of rods to bear upon said plate.

2. A railway tie, comprisin a pair of rail-supporting blocks each formedwith a plurality of horizontally disposed grooves in each of its lateralsides, a pair of tic rods extending in either of said grooves uponopposite sides connecting said blocks together, an apcrturcd plateengaging the outer end of each of said block through which the tie rodsextend to maintain them in close engagement with said grooves, and nutsscrewed upon the outer ends of said rods engageable with said plates.

3. A railway tie, comprising a pair of rail-supporting blocks, a tie rodextending through apertures in said blocks, a pair of tie rods securedupon opposite side walls of the blocks, and an apertured plate engagingthe entire face of each block through which said pair of tie rods aremaintained in opcrative engagement with the blocks.
